Recognising facial expressions images
It is clear to see how the key point changes in different facial expressions in these table and we can also get the scale and proportion from the data through calculation. In this demo the facial expression of a person is automatically extracted from a single picture. The expressions were not only acted out, but subjects were given facial expression images to use as examples to imitate. FaceReader is used at over sites worldwide. However, they only do so when the images are created in a controlled lab setting with consistent head poses and illumination. The if function in Processing, which is a function for qualify in coding language, can help us give a definition to these values. The normal flow rate of the air pump is liter per minute, we use the pressure of 1 bar for the test.

Recognizing Facial Expressions in Image Sequences Using Local Parameterized Models of Image Motion
Journal of Personality and Social Psychology , However, how does webcam can catch the key points on face? With both indigenous groups, he found that study participants did not attribute emotions to faces in the same way Westerners do. This will reduce production costs by preventing impact of health issues on performance. At UK academic institutes, modern facial recognition technology is being used in an attempt to detect different emotional states in pigs. Cite article How to cite?

As a result, in the next step, the author tried to control the angle changing into specific degrees according to level of smile. Identifying the amygdala's role in social cognition suggests insights into the neurological mechanisms behind autism and anxiety. It also proves that emotions can be identified universally from facial expressions; cross-cultural, cross-species, cross-age, which is an important theoretical support for the possibility to detect facial expression by computer vision. The idea of this approach is to capture the transitions between facial patterns over time, allowing these changes to become additional data points supporting classification. This data can be interpreted into some emotions by calculating the key points motions like the scale of the height and width of the mouth or the distance between the two eyes. It would be a bit confusing for the player to realise the changing logic and hard to use more parameters like heart rate to trigger it in the mean time. It turns out that we might communicate better if we saw faces not as mirroring hidden emotions — but rather as actively trying to speak to us.
Nonetheless, after a series of tests we can say that the Webcam has the ability to catch the motion we need in the project at a very low cost. How much air is need for specific angles? For example, higher accuracy can be achieved when classifying a smaller subset of highly distinguishable expressions, such as anger, happiness and fear. The limitation is that the results can not be always precise. Each smile that is being detected can make the angle change by 15 degree.
